As I said, "I want a good quality, ideally hand-held, rotary grater that has a drum with teeth like these:" I already have a couple like the one you linked to.
Yes. I have seen it at the link below and in other places, but it shows as being unavailable. It's not exactly what I want, but it is acceptable and I'd be happy to have it. Note the blade at the upper right.
However, it seems that you've found the grating blade I'm looking for. I will dig a little further into these. The quality of the images are pretty poor and the reviews are quite mixed. I may have to buy one to see and return it if it isn't right. Regardless, your effort is appreciated. Thank you!³
